In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.
In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
In this animated object, learners examine the operation of up-counters and down-counters for a programmable controller. A brief quiz completes the activity.
Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.
Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls, unconditional jumps, and counters in this learning activity.
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
